I did a 4 week prison psyche elective in med school and liked it. There are things I saw as definate downsides and upsides. Downsides where I was included little control over your environment : waiting to get buzzed in through security gates, "secretaries" (prison gaurds) who interrupted any time they wanted, fear of everything being contaminated with hep C, occassionally having to wear stab vests, cinder block walls. Upsides included similar profiles with many of them (lots of mixed bipolars....go figger), decent hours,no call.
Suicides were a trip. One guy on a suicide watch almost killed himself with a spork (one of those plastic fork/spoon combinations) - only about 1/4 of an inch was sticking out of his abdomen, was very close to his abd aorta. How he got the spork nobody is sure. One guy used baby fingernail clippers to snip off all his junk, he was laying in a blood pool and his junk was over in the corner. Wow.
I was in a max security facility (5/5 rating). Very few homocidal guys. Mostly personal drug use (meth). Some of the girls were scarey. One girl who set her little brother on fire among other things - and when we would mention it she would just giggle. One girl was involved in making slash/snuff films - actual films of rape and then they murder the girl on film. Girls are wwaaaayyyyyyy scarier than guys - just like outside the pen. If someone googles my real name pages of information shows up - I was afraid that an inmate would google my name and know all about me and where to find me.
Lots of serious rules. If you let a writing pen get in the hands of an inmate and they do something like make a tatoo with it you can suffer serious legal consequences.
